this is big news
Some may say "meh" since remote access might imply long latencies, but this is InfiniBand. Its latencies are only little more than 1 microsecond, although I'm curious about other overheads in such system employing rCUDA.
For comparison, single context switch in Linux kernel on modern Intel x64 is in the range of 2-3 microseconds, so we are indeed talking low latency access to remote computing resource here. This makes CUDA practical for whole range of new purposes.
